Project Description

This toolkit consists of a set of functions which use information contained within the phase of a Fourier-transformed image to detect localised features such as edges, blobs and corners. These methods have the key advantage that the properties they measure are invariant with respect to image brightness and contrast.

phasecong:Phase congruency using oriented filters
phasecongmono:Fast phase congruency using monogenic filters
phasesym:Phase symmetry using oriented filters
phasesymmono:Fast phase symmetry using monogenic filters

For more information on a particular function, see the associated docstring and the references therein.

Installation

$ python setup.py install

Fast(er) Fourier Transforms

All of the functions in this module make use of the Fast Fourier Transform (FFT), and their speed significantly depends on the module used to provide FFT functions. If it is available, the pyFFTW module will be used. This provides Python bindings to the FFTW C library, and is substantially faster than fftpack, the default for scipy.

To install pyFFTW:

$ pip install pyfftw

Authorship

These functions were originally written for MATLAB by Peter Kovesi, and were ported to Python by Alistair Muldal. The original MATLAB code, as well as further explanatory information and references are available from Peter Kovesi’s website.
